Is your intranet secure? Who is competent to ensure Intranet security?

The enterprise intranet is the ultimate goal and core goal of network attacks. with powerful boundary protection and protection measures, the enterprise intranet cannot be completely secure in the face of increasingly complicated and large enterprise intranets. As long as there are security risks or vulnerabilities in the Intranet, hackers or dedicated organizations can easily bypass the boundaries and directly break into the internal network, infringing on the Intranet security, resulting in loss of enterprise assets, information, and business. How can users quickly, efficiently, and in real time, at a low cost, know whether Intranet assets of the current enterprise are secure and whether they are in a security level? How can we detect threats and fix them immediately to prevent them from happening before they happen?

Is your intranet secure? You need a solid answer.

Intranet asset security definition

Intranet assets of interest in the security field refer to all internal network resources of enterprises that can be remotely intruded and controlled by individuals or groups through technical means for the purpose of destruction or theft, it covers common resources such as personal computers, enterprise servers, and mobile access terminals, meaning common attack targets.

To ensure that intranet assets are not attacked, you need to evaluate the security effect by means of early identification of current network asset threats, early warning of risks, Security Policy reinforcement, and asset threat management and control, this helps users clearly understand the health status of Intranet assets and potential security risks. The intranet administrator can promptly upgrade and reinforce Intranet security accordingly to eliminate potential security risks, and use the suggested border security protection policies, real-time online targeted interception of threat attacks, so as to create an efficient green network environment for users to check, know, and defend against threats.

Who is competent for Intranet asset security?

It involves the network security evaluation market. The first thing that is often mentioned in the industry is traditional vulnerability scanning systems, the principle is to actively identify the system or application version of the Intranet asset device through the system, protocol stack fingerprint recognition, and then analyze the vulnerability situation based on the vulnerability library.

This method can fully exploit vulnerabilities, but the task execution performance and service charges are criticized. For most enterprises, it does not require too much in-depth and comprehensive vulnerability mining. After all, popular attack methods are often single and consistent, such as website Trojan and XSS attacks against browser clients, SQL injection, Web page tampering, and other attacks against Web servers. Enterprises need more real-time, fast, efficient, accurate, and low-cost Intranet asset security identification and evaluation solutions.

In terms of deployment location, technical feasibility, and responsibility positioning, the next-generation firewall, a key edge security device for internal and external network communication, can fully undertake this task.

Identifies Intranet assets of the Next Generation firewall to ensure Intranet security of Enterprises

The next generation firewall is responsible for the security identification of Intranet assets for the following reasons:

1. the next-generation firewall is deployed at the boundaries of enterprise network import and export. In terms of technical feasibility, it can radiate all internal assets and extract security features, in this way, the security of Intranet assets can be dynamically evaluated, estimated, or warned. In terms of performance, with the help of boundary technology and dynamic feature extraction technology, the performance is greatly improved compared with traditional vulnerability scanning technology.

2. when the next generation firewall detects and identifies Intranet risks, it can immediately implement targeted intrusion interception, access restriction and traffic control policies to close the door to Internet penetration attacks, so that enterprises have sufficient time to upgrade the patch system and improve Intranet security.

3. application-based identification, intrusion protection, and traffic management of the Next Generation firewall are notable features that traditional firewalls do not possess. These features are one of the important criteria for assessing whether Intranet assets are secure, such as the use of high-risk applications or abnormal traffic detection, all indicate that the assets are facing an increase in risks.

On this basis, the next generation firewall should have the following main functions for identifying Intranet assets, including:

1. asset risk identification

Multiple asset types, such as PCs, mobile devices, and servers, can be identified based on the network range specified by the user. Evaluates asset security factors, and analyzes the possibility, severity, scope, and difficulty of assets under attack. Performs scoring and report analysis on vulnerable systems and applications, so that you can understand the vulnerabilities of current network assets and resources in real time, outline the vulnerability panorama, and implement targeted vulnerability filling, upgrade patches, firewall policy access control, traffic monitoring, and other security measures to prevent potential intrusion attacks.

2. Security reinforcement solution guidance and implementation

In response to identified asset risks, Alibaba Cloud provides users with the ability to generate one-click security policies. At the network communication level, Alibaba Cloud first strengthens integrated security scanning and protection for communication data with vulnerable assets, and promptly discovers and protects assets in a timely manner, vulnerabilities can be filled, software updates and upgrades are delayed, and responses are slow. Real-Time alerts and recording of intrusion security events are provided to form security event reports and trend charts, and provide users with timely reinforcement and protection.

3. Continuous asset risk assessment

From asset risk identification to implementation of reinforcement solutions, the system will continue to follow up risk prevention and verification results, verify and compare the Implementation Effect of the preventive solution by secondary identification and scoring, related log reports, and tracking and query of Review records. This forms a closed loop from discovery to solution to verification, which greatly reflects the value of our products and customers.

To sum up, Xianzhi is better than Houzhi, and its prevention is better than never before. Help users quickly, efficiently, in real time, and at a low cost to discover the threat of Intranet assets before the attack occurs, so as to promptly fix and upgrade, this is one of the key features that the next generation firewall should undertake and must possess. To some extent, these features save a lot of user investment in attack defense and change users' traditional security defense ideas, it brings great customer value to users in a more active and effective way, which is worthy of reference and reference.
